72.10 - Flat-rolled products of iron or non-alloy steel, of a width of 600 mm or more, clad, plated or coated (+). - Plated or coated with tin : 72 10.11 - - Of a thickness of 0.5 mrn or more 72 10.12 72 10.20 72 10.30 7210.41 7210.49 7210.50 - - Of a thickness of less than 0.5 rnrn - Plated or coated with lead, including terne-plate - Electrolytically plated or coated with zinc - Otherwise plated or coated with zinc : - - Corrugated - - Other - Plated or coated with chromium oxides or with chromium and chromium oxides - Plated or coated with aluminium : - - Plated or coated with aluminium-zinc alloys 7210.69 - - Other 72 10.70 - Painted, varnished or coated with plastics 7210.90 - Other 7210.61 This heading covers the same kind of products as described in heading 72.08 or 72.09, but, to fall in this heading, they must be clad, plated or coated. For the purpose of this heading, the expression " clad, plated or coated " a plies to the products which were subjected to one of the treatments described in Part (C) (2), {ems (d) (iv), (d) (v) and (e) of the General Explanatory Note to this Chapter. This heading excludes : (a) Flat products clad with precious metal (Chapter 71). (b) Products of heading 83.10. Subheading Explanatory Notes. For the purpose of the subheadings of heading 72.10, products subjected to more than one type of coating, plating, or cladding are to be classified according to the last process. However, chemical surface treatments, such as chromating, are not regarded as the last process. Subheadings 7210.30,7210.41 and 7210.49 roducts of subheading 7210.30 have been subjected to the processing described in &) (C) (2) (d) (iv), second indent of the General Explanatory Note to Chapter 72 and the products subheadn s 7210.41 and 7210.49 to any o f the other processing operations described in The Part of part (IV) (c) (5)(4(iv) of that Explanatory Note. To distinguish between roducts electrolytically lated or coated with zinc and products otherwise plated or coated with zinc,the Pollowing procedure can te used : - The products are first to be examined for the presence or otherwise of spangle by visual or microscopic observations. - If span le is detected, they are hot-di ed zinc-coated products. If spangle is not detected, even when magni#ed 50 times, the coating shodfbe chemically analysed. - If aluminium is detected, or lead is detected in excess of 0.5 %, they are hot-dipped zinc-coated products. If not, they are electrolytically zinc-coated products. -
1.- In this Chapter and, in the case of Notes (d), (e) and (f) throughout the Nomenclature, the following expressions have the meanings hereby assigned to them : (a) Pig iron Iron-carbon alloys not usefully malleable, containing more than 2 % by weight of carbon and which may contain by weight one or more other elements within the following limits : - not more than 10 % of chromium - not more than 6 % of manganese - not more than 3 % of phosphorus - not more than 8 % of silicon - a total of not more than 10 % of other elements. (b) Spiegeleisen Iron-carbon alloys containing by weight more than 6 % but not more than 30 % of manganese and otherwise conforming to the specification at (a) above. (c) Ferro-alloys Alloys in pigs, blocks, lumps or similar primary forms, in forms obtained by continuous casting and also in granular or powder forms, whether or not agglomerated, commonly used as an additive in the manufacture of other alloys or as de-oxidants, de-sulphurising agents or for similar uses in ferrous metallurgy and generally not usefully malleable, containing by weight 4 % or more of the element iron and one or more of the following : - more than 10 % of chromium - more than 30 % of manganese - more than 3 % of phosphorus - more than 8 % of silicon - a total of more than 10 % of other elements, excluding carbon, subject to a maximum content of 10 % in the case of copper.
